U.S. Route 412
U.S. Route 412 is an east–west United States highway, first commissioned in 1982. U.S. 412 overlaps expressway-grade Cimarron Turnpike from Tulsa west to Interstate 35 and the Cherokee Turnpike from 5 miles (8.0 km) east of Chouteau, Oklahoma, to 8 miles (13 km) west of the Arkansas state line. It runs the entire length of the Oklahoma Panhandle and traverses the Missouri Bootheel.

Even though the number “412” would indicate that U.S. 412 is a spur route of U.S. 12, the two highways never connect because U.S. 12 runs far more north than U.S. 412. Even though U.S. 412 is a three-digit highway, it is still considered part of the double-digit U.S. Highway System.
